摘　　要：针对华北平原冬小麦-夏玉米种植体系施磷量偏高,在石灰性土壤上磷素利用效率低的问题,提出施用磷肥的土壤有效磷上限,同时集成了以冬小麦季冬前促根、夏玉米季硫酸铵诱导酸化根际土壤为核心的磷肥增效技术。论述该技术的操作规范,旨在优化华北平原冬小麦-夏玉米轮作体系磷肥管理,在保证产量的前提下达到磷肥高效利用。In order to solve the problem of high phosphate fertilizer application rate and low phosphate use efficiency in calcareous soil of winter wheat-summer maize rotation system in the North China Plain,the available phosphors content upper limit of phosphate fertilizer application is proposed,and the technology of root promotion of winter wheat before winter and acidification of rhizosphere soil induced by application of ammonium sulfate of summer maize is integrated.The operational specification of this technique is described in order to optimize the application of phosphate fertilizer and achieve high yield and high use efficiency of phosphate fertilizer in winter wheat-summer maize rotation system in the North China Plain.
